Depending on the scenario both conditions of hypercapnia may be managed with drugs, with mask-based non-invasive ventilation, or with mechanical ventilation. Chronic hypercapnia, where metabolic compensation is generally present, may generate symptoms but is not normally an emergency. Ultimately, the body compensates for the increased acidity by retaining alkali in the kidneys, a process called metabolic compensation.Īcute hypercapnia is known as acute hypercapnic respiratory failure (AHRF) and is a medical emergency as it normally happens in the context of acute disease. The incapability of the lungs to clear carbon dioxide, or inhalation of raised levels of CO2, conducts to respiratory acidosis. ![]() Carbon dioxide may collect in any disease that generates hypoventilation, a decrease of alveolar ventilation (the clearance of air from the small sacs of the lung where gas is exchanged in a particular area) as well as resulting from inhalation of CO2. Hypercapnia (from the Greek word hyper means too much and kapos means smoke), also called hypercarbia (CO2 retention) is a disease of abnormally increased levels of carbon dioxide (CO2) in the blood.Ĭarbon dioxide is a gaseous outcome of the body’s metabolism and is generally expelled via the lungs.
